- Context: In a surprising turn of events, scientists observed the Arctic’s polar vortex spinning in the opposite direction, marking one of the six strongest occurrences of its kind since 1979.
- About Polar Vortex:
- The polar vortex is a large, persistent circulation of frigid air located in the stratosphere and typically centred near the Earth’s poles.
- It is characterized by a strong wind current that circulates from west to east, trapping cold air within the polar regions during the winter months.
- The polar vortex plays a crucial role in maintaining the polar climate and can influence weather patterns in mid-latitude regions.
- Occasionally, disruptions in the polar vortex can occur, leading to phenomena such as sudden stratospheric warming events, which can result in shifts in weather patterns and colder temperatures in regions outside of the polar areas.

Which one of the following statements accurately describes the term &l...
Explanation:
Polar Vortex:
The term 'Polar Vortex' refers to a large-scale circulation pattern that typically forms during winter, trapping cold air within the Arctic region. This phenomenon is not caused by the Earth's tilt on its axis or a high-pressure system over the poles. It is a natural occurrence related to the polar jet stream.
Formation and Characteristics:
- The polar vortex is a circulation of strong winds that normally surround the polar regions in the stratosphere.
- During winter, the polar vortex can weaken, causing it to become less stable and allowing portions of the cold air mass to break off and move southward.
Impact on Weather:
- When the polar vortex weakens, it can lead to cold outbreaks and extreme weather events in regions outside the Arctic, such as the United States and Europe.
- These cold air outbreaks can result in frigid temperatures, heavy snowfall, and other severe weather conditions.
Conclusion:
Understanding the concept of the polar vortex is crucial for predicting and preparing for extreme winter weather events. By recognizing its characteristics and impact on weather patterns, meteorologists can provide accurate forecasts and help communities stay safe during severe cold outbreaks.
